[vtkusers] VTK on two graphics cards?

[Samson Timoner]

Thanks for your help David.

One other question: If I instead wanted to open up two vtk OpenGL 
windows, one covering the entirety of each graphics card, is there a 
command to tell vtk to be full screen on one graphics card?

If not, might you happen to know how can I can query X to get the 
coordinates for a particular monitor/graphics card?

Thanks!

For NVidia cards, all you have to do is set up TwinView in a
side-by-side configuration.  Use nvidia-settings to do this (you can
run it from the command-line or select it from the menu).

For other cards, you might be out of luck.  You can use Xinerama to
make your linux desktop span both monitors, but hardware OpenGL
acceleration might not work in this configuration.  You might have to
use non-accelerated OpenGL instead, and the way this is done will vary
from system to system (on Ubuntu 10.04 the non-accelerated OpenGL is
kept in /usr/lib/mesa).
